[Solved] Vectra C 1.9 CDTI 120KM Mode A: Addressing P2279-11 Error and Intake System Leakage

Hello,
I am new here so please be understanding

I have Vectre C 1.9 cdti with the designation DT or 120km.

The problem with me is a pop-up car with a key when braking the engine from highway speeds. I plugged in and the error P2279-11 popped out, i.e. not tightness in the intake system.
The car was already at 4 mechanics and everyone spreads his hands.
My friend has a vectre with this engine and I replaced:
Przepływkę
Egr
Charging sensor
N75
Only came out of n75 is down so I bought a new ori. The problem is still there.
Turbo is like ok just like the IC hose system. It is surprising that only when braking the engine is a problem. And I'm surprised with the connection of the egr plug itself and the car has a double kick with this holy car with a key. On Saturday I will do the same leak test using sewer pipes (alpha forum) and I will make a plug from a can of beer and visit. One of the mechanics told me that the atmospheric pressure should stand in place I have 97mpa and at the moment cars with the key scale 96 97 and so until the indicator light turns off whether it can be associated with an EGR or a boost sensor. I'm just wondering if my friend has these good parts because one mechanic told me to blow pressure monitoring ... for 250 PLN.

I am asking you for help because I think I have read all the forums and are sneezing ...

tightness of the intake system check the vacuum hoses

Vacuum hoses new as well as turbine control valve. Hoses like a mechanic spr, but I do not download them only visually as I buy sewer pipes and I will make a plug and with a pistol entry, spr under pressure under the hose from the turbine and throttle, if there was a hole, it should hiss even with IC ?? And how to spr arrangement from egr to turbine metal tubes ??

Why is it better to collect car egr plugs after five? Egr is not blinded and a car with a key appears ??

intercoler tightness check how small hole is going to be hissed

So, only to the bathtub with water then it turns out. And after five plugs egr why has more power ?? Replaced and still nothing

Plug in your computer and follow the real parameters. There must be something. With a leaky intake he would have thrown another error. The parameters include boost pressure.

I don't know how to take log dump at op.com to throw here ... Atmospheric pressure 97Mpa at the time of the error jumps 96/97 given top up on slow 104 and I have 98/99
With the dish in the burner, it flattens with yesterday's change of flow, I had a strange situation 440 and I had almost 300 moments before finishing the error and the turbo sections are not topping up. It seems that everything is tight lately the mechanic was checking me. Egr has a ratio of 100% to 4% on slow flow, roughly the same values for the test unless egr me increases the turnover to 1.5 thousand and so keep measuring the resistance egr (to be 4.5 eyes) and spr tube from egr to the collector . Can the exhaust gas cooling system unseal ?? Because it seems to me that this exercise next to the coolant hose is a black goo
Added after 3 [hours] 59 [minutes]:
EGR resistance is 8.4 ohms where in this forum I found that it has to have 4.5 ohms or something is not like to do the op.com test of this electro magnet ??
Added after 12 [hours] 20 [minutes]:
Resistance is ok on pfburgland I found correct values 8 -8.5 I fit, only it is soothed between mechanical and electric power I will clean and drive a little and try to go
